Hi everyone, I seem to have ended up with a disaster of a used car. Sparing the long story of how we ended up with the car, we didn’t pay a lot for it and my friend who didn’t know much about cars conducted the deal. Unfortunately the car is a mess.
For context, we have bought this car for the specific purpose of a trip abroad and then scrapping it at the end or reselling. We are in a region with very poor quality gas. My assessment is the car was very poorly maintained, example being it is missing a cabin air filter and they just duct taped over the hole where it should have been…
The car is a 2000 subaru forester. 182k miles.
What’s the problem?
Acceleration is extremely poor, the car crawls along the street at a low RPM until it eventually rises above 1000, and then it experiences a power surge and functions mostly normally. Sometimes it will go up to 4000/5000 rpm or more before it shifts out of first. Pinging in the engine and under the car has been attributed by various individuals to the bad gas here. (We had to put octane 80 in at one point… and I doubt it was actually 80). Turning off the AC helps the car reach a usable rpm faster.
Very rough idle and stalling at low speeds.
The car overheats while going up mountains/hills.
The coolant is brown, but we have been told it doesn’t have oil in it by a mechanic and by our own smell tests etc.
Check engine light comes on intermittently. (New symptom)
What has been tried?
Knock sensor replaced.
Spark plugs replaced.
Fuel pump replaced.
Fuel filter “cleaned”
Fuel injectors cleaned.
Battery replaced.
Engine air filter cleaned.
We’ve been told we need new spark plug wires and to flush the coolant out, but haven’t been able to find a shop yet that has the correct parts. No one works on subaru where we currently are, but in 2 days we will be able to go to someone that does.
Please, we are at a complete loss here. Is this car just dead or have we missed something? Is there any tests we can do ourselves to try to fix any of these problems?
